On the model of a skew--selfadjoint operator with a simple spectrum on a Hilbert quaternion module

Dmitry Tyshkevich, Irina Karpenko

In this work we construct the model of a skew--selfadjoint operator with a simple spectrum acting on a Hilbert quaternion bimodule. This result is based on the Spectral Theorem for…
